These
materials are very durable and typically last 30 to 50 years if installed
properly. Tile roofs should be installed with synthetic underlayment
and raised with flow through battens or with vertical lath and eave
risers to allow water to flow through to the eaves. Valleys, wall
flashing, eaves, rake and ridge should be laced with ice & water
shield. Tile roofs should be flashed with pan flashing and counter
flashed to keep water on the roof and to protect the interior if water
gets through due to breakage. Tiles are brittle and can be damaged,
so the roof cannot be walked on and should be maintained over time.
